220-1102 Practice Test 8 — 10 Questions

Question 1

A technician is configuring a remote desktop solution for a user who needs to access a Linux server from a Windows 10 workstation. The technician wants to use a secure, encrypted connection. Which remote access technology should the technician configure on the Linux server?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

SSH. SSH (Secure Shell) is the correct choice because it provides encrypted, authenticated remote shell access to Linux/Unix servers over an insecure network. It uses TCP port 22 and supports strong encryption algorithms (e.g., AES, ChaCha20) and public-key authentication, making it the standard secure remote access protocol for Linux systems.

Answer

RDP

Answer

VNC

Answer

Telnet

Question 2

During a security audit, you find that a user's browser has an outdated version of Adobe Flash Player installed. What is the primary security risk associated with this finding?

Accepted Answer

Attackers can exploit known vulnerabilities in the plugin to install malware.. Outdated Adobe Flash Player versions contain publicly known vulnerabilities (CVEs) that attackers can exploit via drive-by downloads or malicious advertisements. Exploiting these flaws allows arbitrary code execution, enabling malware installation without user interaction. This is the primary security risk because unpatched plugins are a common entry point for ransomware, spyware, and botnets.

Answer

The browser will run slower and may crash frequently.

Answer

The user will be unable to view some web content.

Answer

The browser will automatically disable the plugin.

Question 3

A technician is helping a remote user configure a VPN connection. The user is not very technical and is getting frustrated. The technician uses jargon like 'authentication protocol' and 'tunnel endpoint'. Which of the following is the BEST way to improve communication?

Accepted Answer

Use simple analogies like 'a secure tunnel for your data' and guide them step by step.. It replaces confusing jargon with a simple analogy ('secure tunnel') and provides step-by-step guidance, which directly addresses the user's frustration and lack of technical knowledge. This approach aligns with the CompTIA A+ objective of adapting communication style to the audience, ensuring the user understands the VPN concept without needing to know terms like 'authentication protocol' or 'tunnel endpoint'.

Answer

Continue using technical terms to educate the user.

Answer

Ask the user to share their screen so the technician can do it remotely.

Answer

Send the user a written guide and end the call.

Question 4

A technician is configuring a VPN for a remote user. The user's home router uses NAT, and the technician wants to ensure the VPN traffic is encapsulated and encrypted. Which VPN protocol should the technician choose for the best balance of security and compatibility?

Accepted Answer

OpenVPN. OpenVPN is the correct choice because it provides a robust balance of security and compatibility, especially for remote users behind NAT. It uses SSL/TLS for encryption and can operate over a single UDP or TCP port (typically 1194), which easily traverses NAT without requiring additional configuration. Unlike L2TP/IPsec, OpenVPN does not rely on IPsec's NAT-sensitive protocols like ESP, making it more reliable across home routers.

Answer

PPTP

Answer

L2TP/IPsec

Answer

SSTP

Question 5

A company’s change management policy requires that all changes be categorized as standard, emergency, or normal. During a server migration, a technician discovers a critical security patch must be applied immediately to prevent a data breach. Which type of change should the technician request?

Accepted Answer

Emergency change. The scenario describes a critical security patch that must be applied immediately to prevent a data breach, which aligns with the definition of an emergency change. Emergency changes are pre-approved or fast-tracked to address urgent threats or service outages, bypassing the normal change advisory board (CAB) review process. This ensures the patch can be deployed without delay to mitigate the risk.

Answer

Standard change

Answer

Normal change

Answer

Service request

Question 6

A user complains that their Android phone's battery drains extremely fast after a recent OS update. They have already tried restarting the device. What is the most likely cause and solution?

Accepted Answer

The device is performing background indexing; wait a day or two.. After a major OS update, Android devices often perform background indexing of files, media, and app data to optimize search and performance. This process is CPU- and I/O-intensive, causing increased battery drain for 24–48 hours. The correct solution is to wait a day or two for indexing to complete, as restarting alone does not stop this background task.

Answer

The update installed a malware app; perform a factory reset.

Answer

The update reset battery optimization settings; re-enable them.

Answer

The battery is failing due to the update; replace the battery.

Question 7

A technician is called to a user's desk for a 'printer issue.' Upon arrival, the user is on a phone call and waves dismissively at the technician. The technician waits for two minutes, but the user continues their call. What should the technician do?

Accepted Answer

Leave a note on the desk saying you were there and will return later, then check back in 15 minutes.. It demonstrates professional respect for the user's current activity while ensuring the issue is addressed. Leaving a note and returning in 15 minutes maintains a service-level commitment without disrupting the user's call, aligning with CompTIA's best practices for customer communication and time management in a support scenario.

Answer

Stand silently until the user finishes the call, even if it takes a long time.

Answer

Interrupt the call to say you'll come back later.

Answer

Close the ticket as 'user not available' and move on to the next task.

Question 8

A technician is troubleshooting a Windows 10 computer that exhibits strange behavior: system files are missing, and the computer fails to boot normally. A boot-time virus scan detects a virus that infected the Master Boot Record (MBR). Which tool should the technician use to repair the MBR?

Accepted Answer

Bootrec.exe /FixMbr. The Bootrec.exe /FixMbr command writes a new Master Boot Record (MBR) to the system partition, overwriting the infected boot code without affecting the existing partition table. This is the correct tool for repairing a virus-compromised MBR that prevents normal booting on Windows 10.

Answer

System Restore

Answer

SFC /Scannow

Answer

CHKDSK /F

Question 9

A technician is configuring a new Windows 10 workstation for a user who handles sensitive financial data. The company policy mandates that the screen lock after 5 minutes of inactivity and require a password on wake. Which settings should the technician configure?

Accepted Answer

Configure the screen saver to start after 5 minutes and check 'On resume, display logon screen.'. The screen saver settings in Windows include an option to 'On resume, display logon screen,' which locks the workstation after the screen saver activates. Setting the screen saver timeout to 5 minutes and enabling the logon screen requirement meets the policy.

Answer

Set the power plan to turn off the display after 5 minutes.

Answer

Enable the 'Require password on wakeup' setting in the power plan only.

Answer

Set the computer to sleep after 5 minutes and require a password on wake.

Question 10

An iOS user complains that their iPhone will not connect to a known Wi-Fi network, but other devices on the same network work fine. Which iOS-specific troubleshooting step should you perform first to resolve this issue without erasing any personal data?

Accepted Answer

Use the 'Reset Network Settings' option in Settings > General > Reset.. The correct step is to use the 'Reset Network Settings' option in iOS, which clears saved Wi-Fi networks, VPN configurations, and other network-related settings without affecting personal data like photos or contacts. This often resolves stubborn Wi-Fi connection issues. A full factory reset or iCloud restore would be excessive and data-destructive.

Answer

Reset All Settings from the General > Reset menu.

Answer

Erase All Content and Settings to start fresh.

Answer

Restore the iPhone from an iCloud backup.
